resolve an automake warning about subdirs on latest automake

Latest automake will detect then warn if the Makefile uses source
files that are in subdirectories, but the subdirs option is not
set. In the FreeSWITCH build system the current expected behavior is
to expect the subdirs option to be enabled.
